Unlike other research firms which place all major vendors in the leaders quadrant, Radicati Market Quadrants(SM) take a finer view and look only at market leaders. Leading vendors are ranked based on a four quadrant system, which includes "Mature Players," "Specialists," "Trail Blazers," and "Top Players" quadrants. Vendors are positioned based on their market share and the functionality of their solution. Radicati Market Quadrants(SM) provide a comparative viewpoint of the market, and an analysis of each vendor, including both strengths and weaknesses.
